This invention relatesto a new and improved chain-link wire fabric, and more particularly to a fabric of this character designed to resist deformation under strain lengthwise of the fabric. I

Wire fabric of the chain-link type is in wide use andv is manufactured by automatic machines in large quantities. This fabric as generally constructed consists of individual wires or links extending substantially transversely of the fabric and interlinked with adjacent wires. As usually formed, the individual wires are in the shape of a flattened spiral. The portions of the individual wires extend diagonally of the fabric alternately in opposite directions, each wire extending diagonally in one direction until it meets and is interlaced with an adjacent wire when it is reversely bent upon itself and extends 2 diagonally in the opposite direction until it meets and engages with the adjacent wire upon the other side. i 1 I This type of fabric when used for fencing is stretched when secured to the posts and,

5 due to the fact of itsdiamond-shaped mesh, it

' tends to elongate under strain and simultaneously to be reduced in width. The diamondshaped mesh may have, when originally formed, axes transversely and longitudinally of the fabric which are substantially equal.

Under longitudinal strain the longitudinal axis increases in length and the transverse axis of the mesh correspondingly reduces in length. With ordinary type of fencing fabric a strain of only a few hundred pounds may reduce the width of the fabric twenty per cent or more. This characteristic of the fabric makes it diflicult to properly tighten and apply the fabricas a fencing, if its width is to be maintained uniform and corresponding to the original width as woven.

It is an object of the present-invention to provide a chain linkfabric adapted to resist deformation under strain lengthwise of the fabric.

It is an additional object to provide a fabric of this character in which portions of the wire links extend substantially longitudinally of the fabric.

' It is a further object to provide a fabric ric which may of this type having triangular mesh with adj acent.linkshaving their diagonal portions inclined in opposite directions.

It is an additional object to provide afabbe commercially manufactured without material alteration in existing fence machines.

. Other and further objects will appear as the description proceeds. v

I I have illustrated in the accompanyinglfiq. drawings one preferred einbodimentjof'my invention, in which i V j Fig. 1 is a face view of a fragment of the fabric constructed according to my inventiongand Y v .Q is an edge view of the fabric.

In the drawings the'link 11 has its end 12 twisted to lock with the end'13 ofthe link 14. The link ll has the'diagona-lly extending portions 15 and portions 16 e'xtending substantially longitudinallyof the fab-' ric.' The link 1 1 similarly has thedi-agonal portions 17 and substantiallyv longitudinally extendingportions 18. The'di'agonal portions 17 extend .in opposite directionto the diagonal portions 15 of the link 11. As

clearly shown in the drawing,the links are interlaced so thattheir meeting angles are interconnected. These two links may; be taken "as characteristic of the entire fabric and the. adjacent links are similar in, design. Each wire member therefore is provided with reversel y bent portions, the wire or link 11 having such portions 15' and 16, and the wire 14 having the portions 17 and 18. It will be apparent that the wire portions 16 and 18' extend in substantial alinement lengthwise of the fabric, while the alternate portions extend diagonally in opposite directions. As shown in Fig. 2, the fabric is not entirely flattened butthe diagonally extending portions are somewhat rounded as the 7 links interlace. I i 1 In this type of fabric when a strain is put longitudinally of the fabric orsubstantially in line with the link portions 16 and 18, this, strain is resisted by these portions. There is,

therefore, no material'tenden'cy for'the fabric p to be deformed and theshape of the meshes changed under such strain. Under test 2 P 7 I a 1,759,255

thirty-six inch wide-seotionzof this fabric ha'sbeen foundto have' a reduction in width of approximately half an inchr under a strain of fivehundredpounds. The fabric is there 'forewell adaptedfor use Where it must be installed under considerable strain or Where it is desirableto maintain the width of the fabric "substantiallyconstant. i y 'I I While I have shown one preferred form of I V 10 my improved-fabriqitis capable of modificaa V V tion and may be madein'other' forms, the i 1 V f essential features being that portions of the; 7 f
